Abstract

A drive train (1) has an internal combustion engine (2), a traction drive (3), and working hydraulics (4) having at least one hydraulic pump (7). A connecting line (26) leads to a hydraulic accumulator (25) and is connected to a delivery line (10) of the hydraulic pump (7) that leads to the working hydraulics (4). A shutoff valve (30) is located in the connecting line (26). The shutoff valve (30) is a check valve (31) that opens automatically and as a function of the pressure to allow a flow to the hydraulic accumulator (25). A pressure relief valve (32) is operatively associated with the connecting line (26) between the shutoff valve (30) and the hydraulic accumulator (25).
